Where did I get it from? Was it by reason that I attained to the knowledge that I must love my neighbour and not throttle him? They told me so when I was a child, and I gladly believed it, because they told me what was already in my soul. But who discovered it? Not reason! Reason has discovered the struggle for existence and the law that I must throttle all those who hinder the satisfaction of my desires. That is the deduction reason makes. But the law of loving others could not be discovered by reason, because it is unreasonable.
